Mobile device with an image sensing module commonly used by front lens and back lens

Abstract

The disclosure provides a mobile device. A housing comprises an accommodation space. An image sensing module is disposed in the accommodation space of the housing. A front lens is disposed in the accommodation space of the housing, wherein the front lens faces a first direction. A back lens is disposed in the accommodation space of the housing, wherein the back lens faces a second direction and the image sensing module is commonly used by the front lens and the back lens to save cost.

What is claimed is: 
     
         1 . A mobile device, comprising:
 a housing comprising an accommodation space;   an image sensing module disposed in the accommodation space of the housing;   a front lens disposed in the accommodation space of the housing, wherein the front lens faces a first direction; and   a back lens disposed in the accommodation space of the housing, wherein the back lens faces a second direction;   wherein the image sensing module is commonly used by the front lens and the back lens.   
     
     
         2 . The mobile device as recited in  claim 1 , wherein the first direction is a reverse direction of the second direction. 
     
     
         3 . The mobile device as recited in  claim 1 , further comprising a back cover fastened with the housing. 
     
     
         4 . The mobile device as recited in  claim 1 , further comprising a printed circuit board disposed in the accommodation space of the housing. 
     
     
         5 . The mobile device as recited in  claim 4 , wherein the image sensing module is an image sensing chip formed on the printed circuit board. 
     
     
         6 . The mobile device as recited in  claim 5 , wherein the image sensing device comprises a first surface and a second surface, the first surface is reverse to the second surface, the front lens is adjacent to the first surface of the image sensing chip, and the back lens is adjacent to the second surface of the image sensing chip. 
     
     
         7 . A smart phone, comprising:
 a housing comprising an accommodation space;   an image sensing module disposed in the accommodation space of the housing;   a front lens disposed in the accommodation space of the housing, wherein the front lens faces a first direction; and   a back lens disposed in the accommodation space of the housing, wherein the back lens faces a second direction, wherein the image sensing module is commonly used by the front lens and the back lens;   a printed circuit board disposed in the accommodation space; and   a screen disposed on the housing.   
     
     
         8 . The smart phone as recited in  claim 7 , wherein the first direction is a reverse direction of the second direction. 
     
     
         9 . The smart phone as recited in  claim 7 , wherein the front lens and the image sensing module forms a first photograph taking assembly, the back lens and the image sensing module forms a second photograph taking assembly, the first photograph taking assembly and the second photograph taking assembly have the same pixel value. 
     
     
         10 . The smart phone as recited in  claim 7 , wherein the image sensing module is an image sensing chip formed on the printed circuit board, the image sensing chip comprises a first surface and a second surface, the first surface is a reverse surface of the second surface, the front lens is adjacent to the first surface of the image sensing chip, and the back lens is adjacent to the second surface of the image sensing chip.
